COIN- CONTROLLED TICKET-PRINTING WEIGHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 415,294, dated November 19, 1889.

Application filed April 17, 1889. Serial No. 307,569. (No model.)

To all whom it may concern: in Fig. 16 as the ticket is being delivered.

Be it known that I, ERNST GUSTAV IIOFF- Fig. 18 isa front view of the devices shown MANN, a subject of the German Emperor, rein Fig. 17; and Fig. 19, a plan of the ticket-desiding at New Southgate, in the county of livering devices shown in Fig. 16, the print- Middlesex, England, have invented a certain ing-wheels being omitted.

Fig. 16 is a detached View of the In order to keep the pin 19 normally up ticket-delivery apparatus, the parts being in and to regulate the amount of weight which the position in which the ticket is printed. will be necessary to depress it, a spring 20 is 50 Figi17 shows the position of the parts shown attached to a short lever 21, carried by the shaft 14, the other end of said spring being attached to a lever 22, through which passes an adj listing-screw 23, the head of which finds a bearing in the back plate of the coin-chute. When the pin 19 is depressed by the passing of the coin, the finger 12 is free to be moved downward, the slotted portion 114 of the shaft 14 being presented to theline of its travel, as indicated by dotted lines in Fig. 5, and at the same time a second slotted portion 115 of the shaft is brought opposite to a finger 24, carried by a sleeve 26, loosely mounted upon a shaft 17, as indicated in dotted lines in Fig. 7, when the spring 25, attached thereto and to the back of the coin-chute, draws 'said finger in, locking the shaft 14 from further movement, and at the same time turning the sleeve 26 so that the hook 27 becomes detached from the pin 28, carried by the curved arm 29, which, being pivoted on the shaft 30 and attached to the arm 31, is acted on by a spring 32, (attached to the arm 31 and the shaft 33,) which draws it backward until the pivoted projection 34 comes in contact with the pin 35, carried by the rod 1, assuming that the coin has been placed in the machine Without any weight being placed on the scales or platform. If a weight be then placed on the platform, or if it be placed there first and the coin then inserted, the pin 35 will of course be carried down with red 1; but the rapid rotation of the shaft 11 and of the governor (the construction of which is hereinafter described) brings a pin 36, operated by the governor, into the path of a pin 37, carried by the arm 29, which is held so long as said governor is revolving, or, in other words, un-

til the downward travel of the rod 1 ceases;

owing to the Weight 011- the platform being balanced by the springs 4, at which point the parts come to rest, the governor-balls 163 close in, and the pin 36 releases the arm 29, permitting the arm 31 to fall, which it does, at the same time forcing down the frame 3, carrying the printing-rollers, which frame is pivoted on the shaft 38, and acts in a manner hereinafter set forth.

Attached to the-frame 39 is one end of a spring 49, the other end being secured to a lever 41, pivoted on the shaft 30, the tendency of said spring being to draw down the lever 41 and keep the projection 42, carried by the lever 41, resting on the frame 39. lVhen the said frame 39 is in its normal or raised position, being so held by the spring 58, the lever 41 is so raised that the catch 43, carried thereby, is out of contactwith the gear 44, and thereby allows it to turn; but when the frame is forced down by the arm 31 the catch 43 engages with the gear 44 and pre vents it turning, thereby holding the gear 45 on the rotary portion of the two-part shaft 46, on which the prin ting-wheel 47 is mounted.

As will be seen on the drawings, the gear 9 drives the gear 44, which in turn drives the gear 45, which, being secured to the movable part of the shaft 46, causes it to rotate, and with it the wheel 47, which is keyed on said shaft, and in the present case may be taken as being the pound-wheel, bearing 011 its face type indicating from one to fourteen pounds weight. (Here intended to be twice repeated around the periphery.) Said wheel carries a mutilated rim or gear 43, which, as each fourteen pounds is indicated, engages with a pinion 49 on the shaft 50 and turns it one step. Said pinion 49 also engages with a gear 151 on the face of wheel 51,which is here represented as being the stone-printing wheel, and which is loosely mounted on the fixed part of the shaft 46, the arrangement being such that as each fourteen pounds is passed one stone is indicated on the wheel 51, and on the weight being removed from the platform the turning of the gear causes both wheels to return to Zero. It will be evident that the gear may be equally well adapted for the decimal system, where the total weight is indicated solely in pounds, kilograms, or the like.

The wheels 52, 53, and 54 are loose upon the fixed part of the shaft 46, and are intended to indicate the day, the month, and the year, and these may be set daily and secured by set-screws 55, 56, and 57, or driven by clock-work, if so desired, in a manner analogous to that of a calendar-clock.

The spring 58, being attached to a pin on the shaft 30 and a hook 59 on the frame 39, always tends to keep said frame in its raised position, the upward and downward play being limited by a forked arm 60, which is part of the frame 39 and embraces a pin 61, projecting from the main frame.

Referring more particularly to Figs. 10, 11, and 12, which illustrate in detail the governor, 62 indicates the governor-shell, which is secured to the shaft 11. Pivoted in the said shell are the arms 63, carrying the governorballs 163, the rear ends of which rest in a groove or recess in the sleeve 64, which is loose upon shaft 11 and capable of longitudi nal movement thereon against the action of the spring 164, carried in the shell 62, the arrangement being such that as the governor revolves and the arms 63 are thrown out by centrifugal force the sleeve 64 is drawn in, carrying in the forked arm 65, which is pivoted at 66, and embraces a second recess in said sleeve. The arm 65 carries or forms a friction-brake by bringing the points or rubbing-blocks 67 into contact with the disk-face 162 of the shell 62, and when the arms 63 are expanded also brings the pin 36, mounted on said arm, into the path of the pin 37 on the arm 29, as previously described.

The resetting of the machine after a coin has passed through the chute will be best understood by referenec to Fig. 7, in which the dot ted lines indicate the position of the finger -19 and the arms 29 and 31 prior to resetting,

and from this it will be evident that if the IIO - pin 28 on the arm 29, as shown in full lines in Fig. 7.

The lifting of the outer end of the arm 31 is effected by the withdrawal from the machine of the printed ticket in a manner now to be described, reference being made more particularly to Figs. 16 to 19, although the general outlines of the ticket-box and delivery mechanism are indicated in Figs. 6 and 7.

The tickets are arranged in a box or receptacle 17 0, and are carried on a pressure-table 7 O, which keeps the ticket next in order pressed against the top plate 71, which carries a spring-catch 72, adapted to normally hold the sliding plate 73, which, when released from said catch, is drawn forward by the springs 74, to which it is connected by the side arms 76, carrying between them the ticket-pushin g plate 75, which passes beneath a portion of the top plate 71, as most clearly shown in Fig. 17, where a ticket is shown ready for delivery.

An inking-ribbon may be stretched across Y the inner end of the top plate 71, and held in bell-crank lever 82 85, pivoted at 83, until position by the springs 77, beneath which is the bed 78, upon which the ticket rests while being printed.

The cycle of operations is as follows, starting with the parts in the position indicated in Fig. 16: A coin passing down the chute 16 releases the finger 12 and hook 27, and the rod 1 descends until the weight is counterbalanced, when the parts come to rest. The governorarms 63return to their closed position, and the pin 36, which had been in the path of the pin 37, is raised, releasing the arms 29 and 31. The latter, falling, presses down the frame 39. The gear 44 is locked by the pin 43 as the indicated weight on the wheels 47 and 51, with the date on the wheels 52 53 54, is impressed on the card, while the projection 79 on the frame 39 strikeslthe catch 72 and releases the plate 73, which is drawn forward, carrying the printed ticket into the'position shown in Fig. At the same time the nose end 91 of the delivery-plate strikes the frame 92, carrying forward the shaft 81, to which the said frame is secured, and which is supported by the further forward movement is prevented by the arms coming in contact with a stop on the casin g or top plate. The wheels 80, (two of them being shown,) which'are loosely mounted on the shaft 81, are carried forwardtherewith, and, owing to the bell-crank 82, are also caused to descend and grip the card firmly between the said wheels 80 and the rollers 84. As the wheels are unable to go farther forward, the friction, as the card is drawn out by the person who deposited the coin, causes them to rotate in the direction indicated by the arrow in Fig. 17. This movement draws down the crank arms 86, attached to said Wheels, and by the lever 87, with the shaft 88, which is caused to make a partial rotation against the action of the spring 89, attached to the shaft and to the top plate. Secured to the shaft 88 is a bell-crank lever 9095, the forward end 90 of which comes in contact with the end 91 of the delivery-plate 73, which, as the ticket is drawn out, is forced back until it has passed over and been caught by the catch 72, small flat spring attached to the pushing-plate 75,) and provided with a catch 93, engaging with a perforation 94 of the card or ticket next in order, and drawing it back over the bed-plate 7S, ready for being printed. At the same time the rear end 95 of the bellcrank h as come in contact with and raised the arm 31, and consequently the arm 29 has reset the coin and weighing mechanism, while, the ticket being entirely withdrawn, there ceases to be anyfriction on the wheels 80, and consequently the spring 89 resets the parts so that they are in the position indicated in Fig. 16.

The weighing-machine constructed as before described may be used alone or in conjunction with any of the automatic vending apparatuses now in vogue, all that is essential being that the coin should travel from'the coinchute of one machine to that of the other.
